ABSTRACT:
A method and molding tool for the molding of both one- or multi-component parts preferably comprising plastic material which may be integrated together with parts of another material, such as steel and copper, where the turnable middle section during the molding process is supplied with material on at least one of the surfaces thereof, that in contrast to the normal procedures are not at a right angle to the closing direction between the stationary mold part and the movable mold part of the tool. This can be realized by molding a part or a piece of a part and/or by molding around a special part for the in-molding on at least one of these surfaces of the turnable middle section. This molding and/or insertion can take place while the tool is closed and can be performed on several surfaces at the same time in order to save cycle time. The tool according to the invention can substitute or supplement a jaw tool because the turnable middle section in connection with the opening and closing of the stationary mold part and the movable mold part makes these serve as an extra set of jaws.
